Ticks were collected at monthly intervals for 16 consecutive months from individual dogs by their owners in or close to the town of Stellenbosch, Western Cape Province. They were also collected for 27 consecutive months from dogs presented for a variety of reasons at three veterinary clinics in Stellenbosch, and from dogs upon admission to an animal welfare shelter. At one of the veterinary clinics ticks were also collected from cats.
Dog owners collected six ixodid species from their pets and the most numerous of these were Haemaphysalis leachi and Rhipicephalus gertrudae. Twelve ixodid tick species and the argasid tick, Otobius megnini were collected from dogs at veterinary clinics and the animal shelter, and H. leachi, R. gertrudae and Rhipicephalus sanguineus were the most numerous. A total of nine dogs were infested with the Karoo paralysis tick, Ixodes rubicundus. No clear pattern of seasonality was evident for H. leachi, which was present throughout the year. The largest numbers of adult R. gertrudae were generally present from August to October, while adult R. sanguineus were collected during October 2000, February and March 2001, from January to April 2002 and during October 2002. Five ixodid tick species, of which H. leachi was the most numerous and prevalent, were collected from cats.
